What does Cat Warrior 5 tell us?

Cat Warrior doesn't seem to have a five-episode series, does it? According to the encyclopedia, the author has just finished writing the fourth book! These six books are: The Fourth Apprentice, Disappearing Echo, Whispering in the Night, Moonlight Seal, Forgotten Warrior and Battle of the Sky.

I can't understand the English version, but there are still some points in the encyclopedia.

-leafpool became a samurai-Jeffery officially became a witch doctor because of the problems of Ye Chi and crow feathers and the birth of cubs (three brothers and sisters of the Lei family), but she was very unhappy. ...

-Berrynose and Poppy Cream become partners, while honey fern enters the constellation.

-The Astros are at war with the Dark Forest.

The ability of pigeon's paw is that it can see the distance in its heart.

-The green face followed the honey fern into astrology.

Beavers blocked the lake with a dam, so the cat warriors had to cooperate with Qi Xin to destroy the dam.

-Breezepelt gradually developed evil thoughts.

-the tiger of the shadow gate loves the pigeon claw of the thunder gate.

Some people on the Internet say that all six English books have been published, and they are all sold online. It's not right at all. I can't find the five-part, and the six-part doesn't exist. In fact, all the books with the slogan of "Six Episodes Series" are the second, fifth and sixth volumes of the two-part series.
